Fluidized bed furnaces can be divided into spherical arch, flat arch, cone arch and other structural forms according to the refractory lining of the furnace roof. These structures can generally be built with shaped refractory bricks, such as hook bricks,…
What are the commonly used refractory materials? The common refractory materials we widely use in daily life include silica bricks, semi-silica bricks, clay bricks, high-alumina bricks and magnesia bricks. In the field of special materials, we often use high-performance materials…
Refractory materials play an indispensable role in our lives. Whether it is blast furnace smelting, glass manufacturing, or ceramic production, these magical materials are indispensable. So, what types of refractory materials are there? What are their performances? What are refractory…
Refractory materials, as the name implies, are a kind of refractory materials. Strictly speaking, it is widely used, especially in the field of industrial production. At present, many industrial productions require high-temperature technology as support, which is what we commonly…

Clay bricks and high-alumina bricks are different in appearance. Clay bricks are relatively rough, while high-alumina bricks are smoother. High-alumina bricks and clay bricks are not only different in alumina content. Their production processes are similar, but the clinker content…
How strong are lightweight mullite insulation refractory bricks? Mullite insulation bricks can not only play the role of heat insulation, mullite insulation bricks JM-23, JM-26, JM-28, JM-30 series lightweight insulation refractory bricks are a kind of insulation refractory material, which…
During the operation of cement rotary kilns, refractory materials in the kiln are frequently subjected to thermal, chemical and mechanical stresses, which can cause different forms of damage. The consensus reached through the operation practice of cement kilns is that…
The temperature in the AOD furnace is about 1500-1800℃ during smelting. During actual smelting, due to the discontinuity of furnace operation, the temperature difference on the surface of the lining bricks is large, causing intermittent breakage of the lining surface,…
